Using Synclavier® PowerPC™ with OMS

1.
Using Synclavier® PowerPC™ with OMS
Synclavier® PowerPC™ includes a software driver for Opcode System's Open Music
System. This software driver provides "virtual" MIDI ports for MIDI Clock and MIDI
Timecode, the Synclavier® keyboard, and the Synclavier® sequencer.
What is OMS
OMS, or "Open Music System" is a collection of Macintosh utility software that lets you describe your
MIDI hardware setup so that hardware and software purchased from different companies can work
together. The Synclavier® PowerPC™ OMS Driver creates "virtual" MIDI Ports that can send and
receive MIDI data from other Macintosh applications (or hardware devices) without the delays
normally associated with MIDI devices.
What can you do with OMS and Synclavier® PowerPC™
By using Synclavier® PowerPC™ with OMS you can: trigger Synclavier® sounds from any OMS-
aware Macintosh sequencer application or MIDI keyboard; record the Synclavier® keyboard or
sequencer output into a Macintosh-hosted sequencer application; trigger an external MIDI synthesizer
from the Synclavier® keyboard or sequencer; or synchronize the Synclavier® Sequencer to a
Macintosh sequencer using MIDI Clock or MIDI Timecode.
Installing OMS
1) Download latest version of the OMS software from http://www.opcode.com/products/oms.
2) Also download the user documentation for OMS from http://www.opcode.com/dl. In
particular, be sure to download "OMS_2.3_Mac.pdf" and "OMS Making a Studio
Setup.pdf". These documents provide a wealth of useful information about OMS.
3) Install OMS by following the instructions that accompanied the download. You will need to
restart your Macintosh after installing OMS.
4) Move the file "Synclavier® PowerPC™ OMS" into the "OMS Folder" (in your System
Folder) created when you installed OMS.
5) Follow the instructions in "OMS_2.3_Mac.pdf" and "OMS Making a Studio Setup.pdf"
to create your studio setup document.
Installing the Synclavier® PowerPC™ OMS MIDI Driver
Drag the file named "Synclavie® PowerPC™ OMS" from the folder called "OMS Software" into the
folder called "OMS Folder" which is inside your System Folder.
Creating an OMS Studio Setup for Synclavier® PowerPC™
A new Studio Setup is created by selecting the 'New Studio Setup' option from the OMS Setup
application. The Studio Setup created Synclavier® PowerPC™ is shown on the next page.

Synclavier® PowerPC™ OMS Setup
The Studio Setup created for Synclavier® PowerPC™ contains 11 "virtual" MIDI ports that can send and
receive MIDI data to and from other Macintosh applications. Since these are "virtual" MIDI ports, data can
be exchanged at an extremely high speed without incurring the delays normally associated with real
hardware MIDI ports.

The "Synclavier® Keyboard" virtual MIDI Port
The Synclavier® Keyboard virtual MIDI port can send MIDI data in response to notes played on the
Synclavier® keyboard or in response to controller movements from the mod wheel, pitch wheel, breath
controller, pedal 1, pedal 2 or the sustain foot switch. Additionally, MIDI data sent to the Synclavier®
Keyboard virtual MIDI port can trigger Synclavier® sounds as if they were played live.
Sending MIDI Data from the Synclavier® Keyboard
To use the Synclavier® keyboard to send MIDI data to a Macintosh application, you must route the
keyboard MIDI data to the Synclavier® Keyboard virtual MIDI output. This is done either using the
MIDI button on the VK button panel:
or from the MIDI Display (J) screen:
Note: the Synclavier® Keyboard virtual MIDI port always sends and receives data using MIDI Channel 1.
MIDI Input addressed to other MIDI channels is not processed by the Synclavier® Keyboard virtual
MIDI port.

The receiving Macintosh application also must be set up to receive MIDI data from the Synclavier®
Keyboard virtual MIDI port. How this is done will depend on which Macintosh application you are using.
CuBase and CuBase/VST (published by Steinberg) use an input selection dialog box to enable specific
MIDI Inputs. You will see the Synclavier® Keyboard virtual MIDI port appear in the input device list
within your Macintosh application if OMS is installed and set up correctly.

Sending MIDI Data to the Synclavier® Keyboard
The sound that is currently active on the Synclavier® keyboard can be triggered from any OMS-aware
Macintosh application by sending MIDI data to the Synclavier® Keyboard virtual MIDI port. How this is
accomplished will depend on which Macintosh application you are using.
CuBase and CuBase/VST use an output selection button to direct MIDI data to a particular MIDI port:
CuBase and CuBase/VST MIDI Output Device Selection
In order for MIDI data sent to the Synclavier® Keyboard virtual MIDI port to be recognized by
Synclavier® PowerPC™, you must enable OMS MIDI input using the Synchronization panel of the Audio
Event Editor:

Sending MIDI Data from the Synclavier® Sequencer
Use the MIDI Display (J) screen to send MIDI data from a Synclavier® track to its virtual MIDI port:

Sending MIDI Data to the Synclavier® Sequencer
The timbre that is stored on each of the first 120 Synclavier® tracks can be triggered from any OMS-aware
Macintosh application by sending MIDI data to the corresponding Synclavier® Tracks virtual MIDI port.
How this is accomplished will depend on which Macintosh application you are using.
CuBase and CuBase/VST use an output selection button to direct MIDI data to a particular MIDI port and
an intelligent data entry field to specify the MIDI channel number that is used.

In order for MIDI data sent to the Synclavier® Sequencer virtual MIDI ports to be recognized by

Event Editor:

The MIDI Clock and Timecode virtual MIDI Ports
Synclavier® PowerPC™ can send and receive MIDI Clock data through the Synclavier® MIDI Clock
virtual port. Additionally, Synclavier® PowerPC™ can send MIDI Timecode data through the
Synclavier® MIDI Time Code virtual port.
As of Release 4.4 Synclavier® PowerPC™ cannot recognize incoming MIDI Timecode; it can only
generate MIDI Timecode output. Additionally, Synclavier® PowerPC™ cannot send both MIDI Clock
and MIDI Timecode information at the same time. These limitations may be addressed in a later software
release.
Sending MIDI Clock or MIDI Timecode Data from Synclavier® PowerPC™
Sending MIDI Clock or MIDI Timecode data can be activated from the VK button panel by holding the
MIDI button and pressing the SMPTE button. While holding the MIDI button, press the SMPTE button
once for MIDI Clock data, or twice for MIDI Timecode data. Continue to hold the MIDI button and press
the External Sync button to select the timecode frame rate (drop, non-drop, NTSC 30, 25 or 24).
or
After holding the MIDI button and pressing the SMPTE button, use the knob to select which MIDI output
is used to send the MIDI Clock or MIDI Timecode data.
You can also use the Synchronization panel of the Audio Event Editor to turn on or off MIDI Clock or
MIDI Timecode output:

The receiving Macintosh application also must be set up to receive MIDI Clock or MIDI Timecode data
from the Synclavier® MIDI Clock or MIDI Timecode virtual port. How this is done will depend on which
Macintosh application you are using.
CuBase and CuBase/VST (published by Steinberg) use an input selection dialog box to enable specific
MIDI Inputs. You will see the Synclavier® MIDI Clock and the Synclavier® MIDI Time Code virtual
MIDI port appear in the input device list within your Macintosh application if OMS is installed and set up
correctly.

Once the MIDI Clock or MIDI Timecode data is being sent to your Macintosh application, you typically
will have to enable that application to follow an external synchronization source;

Sending MIDI Clock Data to the Synclavier® PowerPC™
Synclavier® PowerPC™ can chase MIDI Clock data being sent to the Synclavier® MIDI Clock virtual
port. As of Release 4.4 it cannot chase MIDI Timecode data.
Use the Synchronization panel of the Audio Event Editor to enable external synchronization to OMS
MIDI:
Or you may activate external synchronization to OMS MIDI from the VK button panel by holding the
MIDI button and pressing the External Sync Mode button:
